Falls off a little with winter **** gas.
Overall I average about 13.5 in mostly city driving.
On the highway it's about 17-19 depending on speed and wind.
The wife's Av has a 5.3 with the same 6 speed trans and 3.42 gears.
It gets about 15 city 19-20 highway.
They both get about 12-13 towing about 6000#.
I would say it's about 10% lower mileage across the board compared to a 5.3.
